BACKGROUND

As the mobile telecommunication industry grows, mobile subscribers arebecoming increasingly more aware of their leverage in the market. Theycarefully compare service providers and call plans, and make educatedchoices before subscribing to a carrier and a service. Subscribers alsocontinuously seek new and improved features to integrate into theirmobile service such as enhanced chat, long distance service options,customized graphical user interfaces and the like.

Despite being informed consumers, mobile subscribers are oftendisadvantaged in the mobile market. For example, although a subscribermay be knowledgeable about their own calling plan subscription,subscribers are usually unaware of the cost per minute of a call to thecalling destination. This puts a mobile subscriber at a disadvantage inmaking educated and economical calling choices.

Mobile subscribers would also welcome more long distance serviceoptions. A subscriber to a telecommunication carrier service typicallyneeds a local access number to utilize the service. This usuallyinvolves selecting a number from a list of regional or area numbers,such as a preprinted list on a calling card, to find the access numberclosest to the subscriber's current location. The subscriber dials thelocal access number and is usually connected to a long distance serviceprovider via a telephony network. Typically, the subscriber can thenenter a target long distance telephone number, and the long distanceservice provider will route the call to a subscriber-specified number.The current approach has many disadvantages, however, such as having topurchase a phone care and locating a local access number. In addition, asubscriber who accidentally places a call using a non-local accessnumber may incur long distance charges.

It is common for a subscriber to experience a significant delay afterpowering on his mobile device before he is able to access updatedcontact information in his address book. This is because the mobiledevice must contact and retrieve an updated contact list from a server.As such, subscribers may desire to access his address book while thecontact information is being updated.

To keep pace with the constant evolution of mobile telephony, mobilesubscribers are treated to a variety of applications designed tooptimize their mobile communication experience. For example, subscriberscan access the Internet with the mobile device, send chat messages totheir contacts and the like. Subscribers can glean relevant andup-to-date information about their contacts in their address books byviewing presence-statuses, away messages, sometimes referred to asstatus messages, mood messages or the like. However, it is common for asubscriber's status message to read the same regardless of which contactviews it. As such, a subscriber cannot customize his status messagebased on the contact who is viewing it.

A mobile subscriber may have one or more contacts in an address bookthat belong to different networks than the subscriber. It is oftendifficult for a subscriber to determine which network a contact issubscribed to, which precludes the subscriber from making informeddecisions about how to optimally call the contact. As such, a subscriberwould like to ascertain to which network a contact belongs so that thesubscriber can optimize call-dialing to this contact.

It is often difficult to determine the origin of a Voice over IP callbecause the call usually does not contain typical country codeidentifiers. As such, service providers would like to determine theorigin of incoming calls to determine whether to accept or reject thecall.

A mobile subscriber may only have limited contact information for acallee. A subscriber may want to obtain further information associatedwith the callee in order to decide how best to contact the callee.

DETAILED DESCRIPTION

FIG. 1 illustrates a flow chart for implementing an exemplary call-costfeature on a mobile device. A mobile device may include mobile orportable devices such as cellular phones, PDAs, media players or thelike. A mobile device may have a processor and a processor-readablestorage medium in communication with the processor.

As illustrated by FIG. 1, a price table database may receive 100 costinformation from a price feed. A price feed provides real time pricinginformation for a product or service. For example, stock prices may beavailable to an online trader via a price feed.

In an embodiment, the price table database may be housed on a computingdevice, such as a server, and the cost information may include the costper minute for a plurality of calling destinations or the like. Table 1illustrates an exemplary price table database according to anembodiment.

TABLE 1 Calling Destination Cost per minute Canada $0.33/minute France$0.56/minute Israel $0.35/minute United States $0.15/minute

The price table database may receive 100 cost information from the pricefeed on a regular basis. In an embodiment, the price feed may include arate sheet provided by a telephone service provider.

In an embodiment, at least a portion of the received cost informationmay be stored 105 in the price table database. For example, the pricetable database may receive a cost-per-minute for calling Canada. If theprice table database does not currently include a cost-per-minute forCanada, the cost information may be added to the price table database.If the price table database includes a different cost-per-minute forCanada, the stored cost information may be replaced with the costinformation from the price feed. In an embodiment, if the received costinformation associated with a calling destination is less than thestored cost information associated with the calling destination, analert may be generated. The alert may be used to notify a subscriber ofthe price discount associated with the particular calling destination.In an embodiment, the server may transmit the alert to a subscriber'smobile device to notify the subscriber of the price discount.

A mapper may use the cost information contained in the price tabledatabase to map 110 cost information to one or more phone numbers in asubscriber's address book. In an embodiment, the mapper may utilizepre-defined rules to map 110 cost information to a contact number. Acontact is an entry in an address book that is accessible by a mobiledevice. A contact number is a mobile device number associated with acontact. In an embodiment, the mapper may map 110 cost information toone or more contact numbers using pre-defined rules. The pre-definedrules may be used to determine, for example, a calling destination,whether the phone number belongs to a landline or a mobile device, orthe like. For example, in Israel, landlines are provisioned with thecountry code +972 followed by an area code ranging from ‘1’ to ‘9’, withthe exception of ‘5.’ Mobile phone numbers typically begin with ‘5.’ Ifa subscriber has the phone number “972-2-5388-0234” in his address book,the mapper may use one or more pre defined rules to determine thecontact number is a landline number is Israel. The mapper may use thisinformation to map the corresponding cost per minute to one or morecontact numbers in a subscriber's address book.

In an embodiment, the mapped cost information may be transmitted to thesubscriber's mobile device for display to the subscriber. FIG. 2 depictsa mobile phone display of exemplary cost information according to anembodiment. As illustrated, the cost to call one or more contacts in asubscriber's address book may be displayed. For example, calling Jim onhas mobile phone costs $0.0136/minute 200, whereas calling Jim on hislandline phone costs $0.017/minute 205. The subscriber may use thisinformation to make an informed calling decision regarding which numberto call.

In an embodiment, cost information may be provided based on associatedcalling plans. As illustrated by FIG. 3, the price table database mayinclude cost information such as mobile providers' calling plans 300, acost-per-minute value 305 associated with the calling plans, a dialingprefix 310 provisioned for each calling plan and/or the like. In anembodiment, the price table database may receive this cost informationfrom the price feed on a regularly updated basis.

In an embodiment, the mapper may map a contact's number with thesubscriber's calling plan and the corresponding cost information may bedisplayed to a subscriber. One or more contacts in a subscriber'saddress book may be displayed with cost information based on thesubscriber's and/or the contact's calling plan. For example, FIG. 3illustrates exemplary information that may be displayed on a mobiledevice. A contact's number 315 may be listed with a cost-per-minutevalue 320 and a calling plan 325 associated with the number 315.

In an embodiment, the mapper may use a contact's phone number todetermine calling destination information such as a contact's locale,whether the contact's number corresponds to a landline or a mobile phoneor the like. After calling destination information is determined, themapper may map at least a portion of the calling destination informationto the subscriber's calling plan. For example, a subscriber may want tocall a contact who has two numbers. The first number may be a landlinein Israel while the second number may be a mobile phone in Israel. Themapper may match the subscriber's calling plan with the destinationinformation to determine that cost information associated with callingthe two numbers.

In an embodiment, multiple service providers may be used to place acall. In such an embodiment, the mapper may map cost informationassociated with all necessary providers so that a combined price may bedisplayed to a subscriber. For example, if a subscriber calls anoverseas contact using a long-distance service provider, thecost-per-minute may reflect both the long distance provider's charges aswell as the local mobile carrier's airtime charges.

FIG. 4 depicts an environment suitable for practicing the illustrativeembodiments. A processor, such as a server 400 may include a mapper 405and/or a price table database 410. The server 400 may be incommunication with a price feed 415 and one or more mobile devices 420via a network 425. The server 400 may be implemented on a stand-alonecomputer system or may be implemented by distributed components such asseparate electronic devices.

In an embodiment, a subscriber may use a local access number to place along distance call. A local access number is a local telephone number asubscriber may employ to connect to a certain long distance serviceprovider. FIG. 5 illustrates an exemplary flow chart of a method forassigning a local access number according to an embodiment. Asubscriber's locale information may be received 500 by a server. In anembodiment, a subscriber may use a mobile device to subscribe to atelecommunication service via a data line. For example, a subscriber mayaccess a browser to transmit an HTTP request. Upon registration, asubscriber may provide locale information such as an area code and atelephone number, a zip code or the like corresponding to thesubscriber's current location. The locale information may becommunicated to a server.

In another embodiment, locale information may be automatically received500 by a server. For example, the locale information may be transmittedvia an HTTP browser to a server where it may be processed by a servicedelivery framework (SDF). The SDF may be aware of the subscriber localeinformation, such as a Mobile Systems International Subscriber IdentityNumber (MSISDN), and may insert such information into an HTTP header.The header may be transmitted to the server where the mapper may extractthe locale information.

In an embodiment, the mapper may map 510 the locale information to adatabase of available access numbers. A local access number may beidentified 520 based on the subscriber's current location and theidentified local access number may be transmitted 530 to thesubscriber's mobile device.

In an embodiment, the mapper may generate a list of long distanceservice providers having local access numbers corresponding to thesubscriber's locale. The server may transmit the list via a data line tothe subscriber's mobile device. The subscriber may select a longdistance service provider, and may receive the corresponding localaccess number on his mobile device.

In an embodiment, the subscriber may use the local access number toconnect to a chosen long distance service provider. The subscriber maymanually input the local access number, followed by the desiredlong-distance phone number. Alternatively, the subscriber may employ anapplication, such as an address book, to automate this process. Forexample, a mobile device's address book may include a long-distanceautomatic dialing feature that allows for quick-dialing of a previouslyentered local access code.

In an embodiment, an existing address book may be populated with thelocal access number for future retrieval. In an embodiment, as asubscriber travels, his mobile device may receive and store new localaccess numbers based on his current location.

FIG. 6 illustrates a method of placing a long distance call using alocal access number according to an embodiment. For example, subscriberwho wants to make a third-party long distance call may register 600 fora long distance service using a browser on his mobile device. Uponregistration, the subscriber may be asked to provide 605 localeinformation, such as a local telephone number with an area code. Thelocale information may be processed 610 by the server, and thesubscriber may receive 615 a list of one or more long distance serviceproviders. The subscriber may select 620 a long distance serviceprovider and may receive 625 a local access number based on the selectedlong distance provider on his mobile device. The subscriber may employthe local access number for as long as he remains in his currentlocation. If the subscriber's address book is equipped with a longdistance auto-dial feature, it may be automatically populated with thelocal access number when the server transmits it to the mobile device.If the subscriber changes locations, he may access his account on thesubscription site, enter a new telephone number and area code, andreceive a new local access number. The subscriber's old access numbermay be stored for later use.

In an embodiment, a local access number may be automatically dialed forthe subscriber, and may or may not require subscriber confirmation. Assuch, the subscriber may only need to specify the preferred longdistance number to call. For example, a subscriber may select or inputthe preferred long distance number to call, and an application on themobile device may place the call by automatically dialing the accesscode local to the subscriber's local information. As described above,the locale information may be ascertained based on the telephone numberprovided by the subscriber at sign-up or by extracting the subscriberlocale information from an HTTP header.

For example, a mobile user who wants to place a long distance call mayselect a contact from his address book to call. The subscriber's longdistance subscription service may ascertain the subscriber's location byextracting locale information from an HTTP header transmitted by thesubscriber's phone or by the locale information the subscriber providedat sign-up. The server may map the subscriber's location to anappropriate local access number which may be sent to the subscriber'smobile device. The subscriber may make one or more selections to dialthe received local access number. Alternatively, the service mayauto-dial the local access number and connect the call without thesubscriber being aware that a local access number has been dialed.

FIG. 7 illustrates a flow chart for an exemplary method of accessingcontact information on a subscriber's mobile device according to anembodiment. When a subscriber first accesses a server-based mobileaddress book application, the subscriber may experience a significantdelay while the address book attempts to retrieve the subscriber'saddress book from the server. In an embodiment, a cache of the addressbook may be created 700 before the subscriber's mobile device is poweredoff. The cache may include contact information stored in thesubscriber's address book during the last application session. Forexample, the cache may include a contact's name, one or more telephonenumbers associated with the contact, a status message associated withthe contact and/or the like.

In an embodiment, a status message indicates whether the contact isonline, offline or the like. A status message includes informationrelating to a status or state of a subscriber, and can be presentedautomatically to anyone who attempts to contact the subscriber. Thestatus message may provide further information regarding the subscriber.In an embodiment, exemplary status messages may include “Having a badday,” “In a meeting,” “At the gym,” or the like.

In an embodiment, the cache may be stored 710 on the subscriber's mobiledevice. When a subscriber powers on his mobile device, at least aportion of the cache may be displayed 720 to a subscriber until a freshupload of contact information can be obtained from the server. Forexample, when a subscriber accesses an address book application afterpowering on his mobile device, the subscriber may be presented with acached version of his address book that may include contacts' names,telephone numbers, status message and/or the like which were stored inthe cache prior to tie mobile device being powered off.

In an embodiment, because the server may take a significant amount oftime to upload a complete fresh address book, contacts may be updated ina particular order according to an embodiment. For example, the firstseveral contacts that appear in a subscriber's mobile device display mayhave their information updated first. Alternatively, priority may begiven to one or more predetermined contacts.

A problem may arise when a subscriber attempts to call a contact'stelephone number using a cached address book. In an embodiment, thecached information may include a contact identification numberassociated with a contact and/or a unique session identification number.A contact identification number is a unique identifier associated with acertain contact in an address book. A session identification number is aunique identifier associated with a calling period. The unique sessionidentification number may remain valid for the length of an entirecalling period, which, in an embodiment, may be the period of time fromwhen the application is powered up and connected until the time that theapplication is powered down. A contact identification number may beassigned to each contact, and may remain valid for the duration of acalling period. In an embodiment, the unique session identificationnumber and the contact identification numbers may expire after thecalling period has closed, thus rendering them invalid for subsequentcalling sessions. As such, when a subscriber attempts to call a contactwith stale status information, the application may attempt to dial inwith an expired session identification number and/or reference anexpired contact identification number, which may result in call failure.While a delay may exist while the server refreshes and updates asubscriber's contact information, a service provider may want to give asubscriber a feeling of being logged onto the network as soon as thesubscriber's mobile device is powered on.

For example, in an embodiment, if a subscriber selects a contact fromthe cached address book having expired status information, the contact'sphone number may not be immediately dialed. Instead, the subscriber'smobile device may dial a server and may dispatch the name of the desiredcallee across a network. The server may send back a sessionidentification number to be utilized during the calling period and/or acontact information number that references the callee. In an embodiment,the server may also send a local access number to be used to contact thecallee. Alternatively, the call may be completed without the use of alocal access number.

In an embodiment, if a subscriber selects a contact from the cachedcontact list having stale status information, a prepare call may be sentto the server. The prepare call may include a session identificationnumber, a callee's contact identification number, a callee's contactname and the like. The server may send back a new session identificationnumber for the subscriber, a contact information number that referencesthe callee, a local access number to be used to contact the calleeand/or the like.

In an embodiment, if a subscriber selects a contact from the cachedcontact list having stale status information, a direct inward dialing(DID) number of the callee may be directly dialed, and the dual-tonemulti-frequency (DTMF) tones of the caller may be appended to adial-string associated with the call. A DID number is a feature offeredby telephone companies for use with customer's private branch exchange.A telephone company may allocate a range of numbers all connected to thecustomers' PBX. As the PBX receives calls, the number that the callerdialed may also be presented so the PBX can route the call to the targetcallee. For example, DID numbers may be obtained by administrators of aVoIP network and assigned to a gateway in the network. The gateway mayroute incoming calls from the network to appropriate VoIP subscribers.

In an embodiment, a set of DIDs may be assigned to a gateway. Thegateway may then reassign the DIDs to a particular mapping ofcaller-callee. For example, Caller A may have ten contacts, A-K. Eachcontact may be assigned a unique DID number. When Caller A selects acontact from his cached contact list, Caller A is, in effect, selectingthe DID number associated with the contact.

In an embodiment, if a subscriber selects a contact from the cachedcontact list having expired status information, a callee's DID numbermay be directly dialed, and the DID number and the identification numberof the caller may appear within the dial-string.

In an embodiment, a subscriber may use an address book on thesubscriber's mobile device to call one or more contacts stored in theaddress book. The subscriber may communicate with these contacts bydialing the contact directly, by sending chat messages or the like. FIG.8 illustrates an exemplary system for implementing mobile address bookinteraction according to an embodiment. In addition to being storedlocally on a mobile device 800, the contact information in asubscriber's address book 805 may also be cached on a server 810 whichmay regularly update the address book information. The server may sendinformation about the subscriber's contacts to the subscriber's mobiledevice 800 as it become available. In an embodiment, the subscriber'smobile device 800 may poll the server at specified intervals to receiveupdates about the subscriber's contacts. Updated information may beintegrated into the subscriber's mobile address book 805 for thesubscriber to access. In an embodiment, contact information may includea status message or the like.

As FIG. 8 illustrates, bi-directional communication 815 may existbetween the server, the subscriber's mobile device and the contacts 820who appear in the subscriber's address book. In an embodiment, theserver may push information, such as a status message associated withthe subscriber, to the contacts 820. The server may also pullinformation from the contacts 820 for transmission to the subscriber'smobile device.

For example, if the subscriber wishes to change his status message, thesubscriber may set a new status message using his mobile device. The newstatus message may then be sent to the server to be propagated to thesubscriber's contacts. When the server receives and processes the newstatus message, the server may send the new status message to all of thesubscriber's contacts.

FIG. 9 illustrates a method of providing contact information accordingto an embodiment. A server may receive 900 one or more status messages,such as a holographic message, from a subscriber's mobile device. Aholographic message relates to customized messages that differ based onwhich contact inquires about the subscriber's status. That is, differentcontacts may be presented with different messages depending on theidentity of the contact. The present discussion is intended tocomprehend a one-to-one correspondence between messages and contacts,but is not so limited, and also includes messages directed to subsets ofmore than one contact. For example, a subscriber's holographic messagemay read “I'm in a meeting” to work colleagues, but may read “I'munavailable” to all other contacts.

In an embodiment, a subscriber may set a holographic message using thesubscriber's mobile phone. The subscriber may identify a message for aspecific contact. For example, a subscriber may set a holographicmessage that reads “I'll be home at 6:30 pm” to his wife. The subscribermay also set a holographic message for a specific contact group. Forexample, a subscriber may set a holographic message that reads “At thebeach” to his friends.

In an embodiment, the holographic messages set by a subscriber may besent to the server to be transmitted to the contacts in the subscriber'scontact book. The server may store 910 a holographic message andcorresponding contact or contact group. The server may transmit 920 theholographic message to the mobile phones of the appropriate contactsbased on the contact's name, the contacts group or the like. In anembodiment, the server may integrate 930 the holographic message into anaddress book associated with a contact. The server may transmit one ormore instructions to a contact's mobile device instructing the mobiledevice to display the holographic message.

In an embodiment, a list of most-recently called contacts may be kept.For example, the list may reflect the last ten contacts a subscribercalled, chatted with, changed a status message for, or the like.Typically, a subscriber's address book is stored on a server, and a pushpresence technique is utilized to access contact information, such as astatus message or the like. In an embodiment, the push presencetechnique requires a subscriber to retrieve the latest contactinformation from the server. However, a subscriber who as many contactsmust access the server numerous times in order to view contactinformation, which may drain the battery of the subscriber's mobiledevice. As such, a list of most-recently called contacts may be kept.This list may be stored on a subscriber's mobile device or on theserver. If the list is stored on the server, the server must only pushthe contact information associated with the contacts in themost-recently called list instead of the contact information for everycontact in the subscriber's address book.

In an embodiment, a gateway may decide to accept or reject a call basedon the call's point of origin. For example, a call may originate in onecountry and terminate in a different country. FIG. 10 illustrates adiagram depicting a call originating in one country and terminating in adifferent country according to an embodiment. FIG. 11 depicts a flowchart of an exemplary method of determining a call's point of originaccording to an embodiment.

In an embodiment, a caller may select 1100 a contact to call via thecaller's mobile device. As illustrated by FIG. 10, the caller 1000 maybe located in the United Kingdom, while the callee 1005 may be locatedin Germany. The call may be sent from the caller's mobile device 1010and received 1105 by a caller gateway 1015, or a gateway associated withthe caller's location. In an embodiment, the caller gateway may resideon a server. In the example illustrated by FIG. 10, the callee gateway1015 is a UK Gateway 1015. The call may be transmitted 1110 over anetwork 1020, and may be received 1115 by a callee gateway 1025, or agateway associated with the callee's location. In an embodiment, thecallee gateway may reside of a server. In the example illustrated byFIG. 10, the callee gateway is a Germany Gateway 1025. In an embodiment,the callee gateway 1025 may process the call as a mobile-terminated callto the callee's mobile device 1030.

In an embodiment, a callee gateway may determine 1120 whether to acceptor reject a call based on the origin of the call. In an embodiment, outof band signaling may be employed 1125 to make this determination. In anembodiment, a first communication channel may be created to bridge thecall. The first communication channel may be a standard communicationchannel. In an embodiment, the first communication channel may be HTTP.In an embodiment a second communication may be created. The secondcommunication channel may serve as a communication channel between aplurality of servers. In an embodiment, before a call is transmitted, anHTTP request may be transmitted to one or more servers on the secondcommunication channel alerting the servers of the origin of the call.For example, in the example illustrated by FIG. 10, a caller may selecta contact from an address book. Before the call is transmitted, an HTTPrequest may be transmitted to one or more servers on the communicationchannel alerting the servers that the call about to be processed isoriginating from the United Kingdom. As such, the alerted servers willbe notified as to the call's country of origin before the call reachesits final destination.

In an embodiment, in-band signaling audio may be employed 1130 toidentify the origin of a call. In an embodiment, one or more DTMF tonesmay be used to identify the origin of the call. Before a call isconnected to a callee, one or more DTMF tones may be inserted into thecall. These tones may be heard by the callee as a series of pings. In anembodiment, the DTMF tones may be encoded to represent the country oforigin. The server that receives the call may interpret the DTMF tonesto ascertain the country of origin. An indication of the country oforigin may be transmitted to the callee gateway, which may determinewhether to accept or reject the call.

In an embodiment, in-band signaling non-audio may be employed 1135 todetermine the origin of a call. In an embodiment, the network may employan audio channel and a data channel. The data channel may be used forsending data as well as a protocol for allowing the caller gateway andcallee gateway to communicate with each other. In an embodiment,information associated with the call origin may be sent to the calleegateway via the data channel. In an embodiment, the origin informationmay be sent in a text message, in a data message or the like. In anembodiment, a data message may include a data protocol or the like.

In an embodiment, after the country of origin is ascertained from anincoming call, the callee gateway may use this information to decide1120 whether to accept or refuse a call. If the call is accepted, thecall may be routed 1140 through the callee gateway to the callee'smobile device. If the call is refused, the callee may be alerted 1145that the call could not be completed.

In an embodiment, a caller may use a portion of information regarding acallee to ascertain other information pertaining to the callee. Forexample, a caller may know a DID number corresponding a contact,however, the caller may be unaware of the contact's screen name, accountname, email address or the like. If the caller directly dials thecontact's DID number, he may incur long distance charges that he may notincur if he contacts the callee via the callee's screen name.

FIG. 12 illustrates a flow chart of an exemplary method of determininginformation associated with a callee according to an embodiment. FIG. 13illustrates an exemplary diagram of determining information associatedwith a callee according to an embodiment.

In an embodiment, a caller 1230 may dial 1200 a DID number associatedwith a callee 1235. The DID number may be received 1205 by a serverwhich may compare 1210 the DID number to one or more entries in aconsolidated general registry 1240. In an embodiment, a consolidatedgeneral registry 1240 may include contact information associated with asubscriber, such as the subscriber's telephone number, screen name,email address and/or the like and may reside on a server. The server mayuse a portion of information transmitted from a caller to identify 1215other information corresponding to the callee 1235. For example, if acaller 230 dials a callee's DID number, the consolidated generalregistry 14 may use the DID number to determine that the callee 1235also has a screen name. In an embodiment, at least a portion of thecontact information may be transmitted to the caller. In an embodiment,one or more images, such as the transmitted contact information, may bedownloaded to a mobile device in one or more stages. In an embodiment,an images may be downloaded progressively in one or more stages as theuser continues to use the mobile device. In an embodiment, an image maybe displayed in low resolution in a first stage, but with eachsubsequent stage, the image quality associated with the image mayprogressively improve. For example, when a user first powers on hismobile device, the user's address book may appear in low resolution.After a certain period of time, the resolution and image quality mayimprove. After a certain period of time, the image quality andresolution may further improve.

Table 2 illustrates an exemplary entry in the consolidated generalregistry according to an embodiment.

TABLE 2 DID Number Screen Name Email Address 1 Email Address 23024562786 isapr25 isapr25@aol.com isapr25@gmail.com

For example, if a caller 1230 wants to contact the callee 1235identified by Table 2, he may dial the callee's DID number because thisis the only contact information he has regarding the callee 1235. Theserver may match the received DID number to the screen name isapr25 asillustrated by Table 2. The callee's screen name may be transmitted 1220back to the caller 1230 and the caller 1230 may be provided the optionof contacting the callee 1235 using her screen name. In an embodiment,the call may automatically be completed 1225 using a predeterminedmethod. For example, the call may be completed using the least expensivemethod. In an embodiment, the call may be transmitted through a gateway1245 which may connect the call to the callee 1235.

In an embodiment, call dialing may be optimized so that a call isprocessed more efficiently. Optimization may involve identifying towhich provider a caller and a callee belong, and deciding how to route acall between the two based on at least the provider information and costinformation.

FIG. 14 illustrates a flow chart for an exemplary method of optimizingcall dialing according to an embodiment. In an embodiment, a caller mayselect 1300 a contact from an address book. A first call, such as aprepare call, may be sent 1305 to a server. In an embodiment, the firstcall may include one or more of a session identification number, acallee's contact identification number, a callee's contact name, a DIDnumber and the like. In an embodiment, a DID number may include one ormore of a country code and a unique identifier associated with themobile provider.

In an embodiment, the server may use the information contained in thefirst call to determine how to best optimize call dialing. For example,the server may determine 1310 a provider associated with the caller anda provider associated with the callee. In an embodiment, if a caller anda callee are subscribers to the same provider, the server may connect asecond call using direct dial. In an embodiment, the second call may bea voice call. For example, if the caller is a subscriber to Provider A,and the callee also belongs to Provider A's network, the server mayautomatically connect the caller to the callee's number.

In an embodiment, if a caller belongs to a different network than thecallee, the server may provide an access number that may serve as agateway through which to connect to a third party provider network, suchas a third party VoIP provider network. In an embodiment, an accessnumber may be returned to the caller. The caller may dial the accessnumber to reach the callee. Routing the second call through a thirdparty network may reduce the charges incurred and the call may beprocessed more quickly and efficiently.

In an embodiment, a mapper, such as that illustrated by FIG. 1, may usethe cost information contained in the price table database to map 1315cost information to the callee's phone number. For example, if a callerdials a callee that has two possible phone numbers, the server maydetermine 1320 how to optimize call dialing by determining whether thecallee is a subscriber of the callee's network for either phone numberand the cost information associated with the callee's phone numbers. Theserver may use this information to call 1325 the callee.

In an embodiment, a mobile device may include a filter that sorts one ormore contacts in an address book based on certain criteria. FIG. 15illustrates an exemplary graphical user interface illustrating a filteraccording to an embodiment.
